Applicant's summary and conclusion

Conclusions:
No adverse effects on reproductive organs or tissues were observed in a subacute oral study with rats up to and including 1000 mg/kg and bw.
Executive summary:

In a repeated dose toxicity study in rats (Wistar, OECD TG 407) the substance was administered via gavage to 5 rats/sex/dose at 0, 100, 300, 1000 mg/kg bw in PEG 400 for 4 weeks. Up to and including the limit dose of 1000 mg/kg bw neither gross pathological nor histopathological changes of the male and female reproductive organs (testes, epididymides, prostate, seminal vesicles incl. coagulation glands, ovaries with oviducts, uterus with cervix, vagina, mammary glands) were reported. Overall, based on the subacute toxicity study there is no indication of a reproductive toxicity potential of Desmorapid 01 and the NOAELfor reproductive effects for male and female rats can be considered as 1000 mg/kg bw.
